"I used to spend hours putting together quotes. BuilderCalc gets me to an accurate figure in minutes — it's paid for itself ten times over on my very first job."
"The regional pricing is spot on. I was sceptical at first but compared it to my own rates and it's genuinely accurate for the Midlands. Recommended to all my subcontractors."
"As a homeowner, I had no idea what my extension would cost. BuilderCalc gave me a solid ballpark before I even spoke to a single contractor. Brilliant tool."
Our estimates are based on current 2026 UK market rates sourced from industry data and real contractor pricing. They are designed to provide a professional indicative figure — typically accurate to within 10-15% of final tender prices. For detailed specification builds, we recommend following up with a qualified quantity surveyor.
